Fluid Intake

Before Exercise

  • Drink upon waking and continue to sip fluids little and often to ensure you are hydrated before exercise.
  • An isotonic sports drink can offer additional energy and can be useful if you struggle to consume adequate food prior to exercise.
  • A meal three to four hours before exercise should be relatively low in fat and fibre, high in carbohydrate and contain a moderate amount of protein.
  • If needed, eat a high carb snack 30-60 minutes before exercise.

During Exercise

  • Drink according to thirst to prevent dehydration (more than a 2% body weight loss).
  • For light to moderate exercise for short periods, water should be sufficient.
  • Include electrolytes (sodium) for exercise in the heat or exercise that lasts more than 60 minutes.
  • For hard exercise lasting more than 60-90 minutes you can consume carbohydrate foods to provide a source of readily available energy. This is usually in a fluid or gel form.

After Exercise

  • Replace ~120-150% of fluid loss (calculate by weighing yourself pre- and post-exercise).
  • include electrolytes to help retain the fluid you are drinking. This can be in a drink, snack or as part of a recovery meal.
  • After an intense or prolonged session, carbohydrate foods will help replenish the carbohydrate (glycogen) stores used during exercise.
  • The addition of protein, especially after resistance exercise, will provide amino acids for the building and repair of muscle tissue, 15-25 g is sufficient.

Be Prepared. Things go wrong. Times get moved. Rain stops play. Be prepared and do not let these changes interfere with your preparation. Always travel to a competition with enough food and drink to cover every eventuality.
